As your baby grows, you can easily adjust the height, leg position and seat area. The pressure-relieving waist belt sits at waist height when you carry your little newborn baby, and as your baby grows larger, you move the belt down to your hips. Before your baby can hold their head up unaided, good head support is essential to help hold their head in an upright position. Baby Carrier Harmony has a head support with three different positions, which you easily adjust using the poppers. Use the position that provides good head and neck support, and gives you good supervision of your baby.
